The lore, from an old botany professor, is that Siberian natives (somehow watching Caribou, who are said to love the stuff) learned you could "recycle" the stuff (being reindeer pee) for quite a while by reclaiming your urine. Muscimol being excreted unchanged, supposedly, means the shaman-equivalent could trip continuously while offering "sacraments" to others in the group (at least till tolerance set in). You have to remember this is Siberia, what else are you going to do during the winter, besides drink random reindeer pee to try to get high?
So, anyone heard anything like that, or am I just spreading disinformation (although, is it even available here)? (Also, doesn't sound pleasant, should be MUCH different than Psilocybe, more like Datura, and with a much worse safety profile.)
Oh, and if it's not excreted unchanged, is it modified by passing through a reindeer first?
